As long as it prepped right the newer QUALITY clears shouldn't flake off for many many many many years (that's many times four) as long as it's waxed fairly often and not out in the desert all day 24/7. We sell a clear at work for $65 gallon of clear and the hardner used car lots love it but if you spray it today it will probably peel by Easter. Quality clears have come along ways in the last 15-20 years or so it's the same as cell phones. Your phone you have today it's not the same as that phone in a bag we had in '94.

Now that I know you have a detailing background I semi get your reluctance. I have delt with almost as many car dealer make readies, detail shops and body shop detalers as I have paint body guys since we cater to both at my employer. I still feel BC/CC is the only way to go.
